Air Fryer Mozzarella Sticks

Ingredients

• 12 stickspart-skim mozzarella string cheese
• 3 tablespoonsplain flour
• 1 largeegg
• 30 ml (2 tablespoons)skimmed milk or milk of choice
• 80 g (⅔ cup)Italian-seasoned breadcrumbs, wholemeal if possible
• 20 g (⅓ cup)panko breadcrumbs
• 1 teaspoonItalian seasoning
• ¼ teaspoongarlic powder
• as needednon-stick cooking spray or olive oil spray
• for servingmarinara sauce or ranch dressing

Instructions

1. 1

   Freeze the cheese

   Cut each cheese stick in half crosswise to make 24 pieces. Arrange them in a single layer on a parchment-lined baking sheet, board or plate, then freeze until completely solid, about 1 hour.

2. 2

   Prepare the flour

   Once the cheese is frozen, put the flour in a shallow dish. In a separate shallow dish, whisk together the egg and milk.

3. 3

   Mix the crumbs

   In a third shallow dish, combine the Italian breadcrumbs, panko, Italian seasoning and garlic powder. Set the dishes in order—flour, egg, then breadcrumbs—and line a large, rimmed baking sheet with parchment.

4. 4

   Coat the cheese

   Work with 2 to 3 frozen cheese pieces at a time. Dredge them in flour and shake off the excess, dip them in the egg, then place them in the crumbs and gently pat to coat. Avoid coating too many at once, as the egg can freeze onto the cheese and stop the crumbs sticking.

5. 5

   Freeze again

   Place the coated pieces on the prepared baking sheet and repeat until all the cheese is breaded. Return the tray to the freezer for at least 1 hour; this is essential to help the coating turn golden before the cheese melts.

6. 6

   Arrange in basket

   When ready to cook, preheat the air fryer to 199°C (390°F). Generously spray the basket, then arrange the frozen sticks in a single layer with space between them; cook in batches if needed. Spray the tops of the sticks as well.

7. 7

   Air fry and serve

   Air fry for 6 to 8 minutes, until the cheese is heated through and the crumbs are golden. Transfer to a plate and leave to stand for 3 minutes; they will be very hot. Cook the remaining batches and serve warm with marinara sauce, heated first if desired, or ranch dressing.

What are mozzarella sticks?

Mozzarella sticks are a popular American appetiser: pieces of mozzarella are coated in crumbs and cooked until crisp outside and soft inside. This air fryer version uses string cheese, which is easy to portion into uniform sticks.

Italian-seasoned crumbs, panko and a little garlic powder give the coating savoury flavour and crunch. Freezing the cheese both before and after breading helps the coating brown before the centre escapes.

Nutrition and macros by portion

The nutrition label shows one serving as written: 54 calories, 4g protein, 2g carbs, 3g fat.

The mozzarella provides most of the protein and fat, while the flour and breadcrumbs supply most of the carbohydrates. Pair a serving with vegetables or salad for a more balanced plate, and serve the dip on the side so you can choose how much to use.

Why use two kinds of crumbs?

Italian breadcrumbs: These provide the main seasoned coating and help cover the cheese evenly.

Panko: The larger, airy flakes add a more textured crunch. Mixing the two gives the sticks a crisp surface without relying on panko alone.

The coating sequence

Flour first: A light dusting helps the egg cling to the frozen cheese. Shake off any extra so the coating does not become patchy.

Egg, then crumbs: Work in small batches and pat the crumbs gently onto each piece. If the egg freezes onto the cheese before the crumbs go on, it may no longer be sticky enough to hold them.

Why the second freeze matters

Chill the breaded sticks for at least 1 hour before air frying. This gives the coating time to set and keeps the cheese from melting too quickly during the short cook.

Keep the pieces frozen until the air fryer is ready. Cook in batches if necessary so there is room around each stick for the hot air to circulate.

Look for golden crumbs

At 199°C, the sticks take 6 to 8 minutes. Check for a golden crumb coating and heated cheese, and avoid extending the cooking time unnecessarily, as the filling can leak out.

Leave them to stand for 3 minutes after cooking. The cheese inside is very hot, and a brief rest also makes the sticks easier to handle.

Serving and dipping

Serve the sticks warm with marinara sauce or ranch dressing for dipping. Warming the marinara first makes it a more inviting contrast to the hot, crisp coating.

For a more substantial snack plate, add a simple green salad or sliced vegetables alongside them.

Recipe notes & tips

• Make sure the cheese pieces are fully frozen before dipping them.
• Set out the coating dishes in order before you begin breading.
• Coat just 2 to 3 sticks at a time so the egg remains tacky.
• Freeze the breaded sticks for at least 1 hour before cooking.
• Leave space between sticks in the air fryer basket and cook in batches.
• Rest the cooked sticks for 3 minutes before serving.

Variations

• Wholemeal crumbs: Use wholemeal Italian-seasoned breadcrumbs as suggested for a more robust coating.
• Extra garlic: Add a little more garlic powder to the crumb mixture for a stronger savoury note.
• Herb change: Swap the Italian seasoning for another dried herb blend you enjoy.
• Marinara dip: Warm the marinara sauce before serving for a cosy contrast.
• Ranch dip: Serve with ranch dressing instead of marinara, or offer both.

Common mistakes to avoid

• Skipping the first freeze: The cheese needs to be solid before coating; freeze it for about 1 hour.
• Coating too many at once: The egg can freeze onto the cheese; work with 2 to 3 pieces at a time.
• Missing the second freeze: The cheese may melt before the crumbs turn golden; freeze the coated sticks for at least 1 hour.
• Crowding the basket: Sticks that touch have less room around them; cook in batches in a single layer.
• Cooking for too long: The filling can escape; check at 6 minutes and cook up to 8 minutes as needed.

How to store

Cool any leftovers, then store them in an airtight container in the fridge for up to 3 days. Reheat in the air fryer until hot and crisp; the coating may soften during storage.
